Reported for being a high hitter?

The other day I was doing a 2v2 fight in pvp the other day with my ice friend (I was ice too so we were both ice). After a long time of getting rid of shields and getting blades and converts set, my friend used a Colossus on the last guy who was there (balance wizard), and he was instantly killed after the colossus hit over 10,000. I know for a fact that we never said anything bad, and then the dude reports us. He reported my friend first and I don't know if he reported me because after the victory screen showed up I lost connection so it's beyond me if I was reported. :x
